THERMOPLASTIC RESIN COMPOSITION AND COMPOSITE MOLDINGS

摘要

A thermoplastic resin composition capable of providing composite moldings which are excellent in chemical resistance and surface appearance, in the close adhesion of surface layers made of the composition to substrate resins such as PS resin or waste thereof, and in fabricability (such as chipping resistance) and endurance (such as heat cycle resistance); and composite moldings with surface layers made of the composition. A thermoplastic resin composition comprising 100 parts by mass of the first vinyl (co)polymer (I) which is obtained by (co)polymerizing one or more monomers selected from the group consisting of aromatic vinyl compounds, vinyl cyanide and other vinyl monomers copolymerizable therewith and 1 to 100 parts by mass of a vinyl copolymer (II) which is obtained by copolymerizing vinyl cyanide with other vinyl monomer copolymerizable with vinyl cyanide and in which the vinyl cyanide content of the acetone solubles is 0.1 to 15% by mass.
